Power Cable Gauge Guide
The gauge of wire needed to connect the stereo to power and ground depends on the power source and the length of the cable run from the power source to the stereo. Refer to this table to determine the appropriate wire gauge for your installation. This table accounts for terminal connection resistance.
NOTE:
If you are using aluminum wire, you should use a wire two gauges larger than the gauge listed below to compensate for a potential voltage drop due to the wire material.
